It doesn’t look like it produced many pistils, so the bud formation is a bit light. What type of light are u using? I doubt you’re gonna get much more density if the light isn’t strong enough. Get yourself a cheap jewelers loupe and look at the trichome heads on the center parts of the buds. If you’re not spitting off any new white pistils and those trich heads are at least 75% cloudy, u can safely harvest without losing much upside.
A pic of the entire plant would help everyone give u the best advice possible. It’s hard to tell any scale without a full pic. Those buds could be the size of marbles…..or golf balls. That makes a difference.
